=head1 DESCRIPTION
By default F<bisect.pl> will process all options, then use the rest of the
command line as arguments to list C<system> to run a test case. By default,
the test case should pass (exit with 0) on earlier perls, and fail (exit
-non-zero) on I<blead> (note that running most of perl's test files directly
-won't do this, you'll need to run them through a harness to get the proper
-error code). F<bisect.pl> will use F<bisect-runner.pl> to find the earliest
-stable perl version on which the test case passes, check that it fails on
-blead, and then use F<bisect-runner.pl> with C<git bisect run> to find the
-commit which caused the failure.
+non-zero) on I<blead>. F<bisect.pl> will use F<bisect-runner.pl> to find the
+earliest stable perl version on which the test case passes, check that it
+fails on blead, and then use F<bisect-runner.pl> with C<git bisect run> to
+find the commit which caused the failure.
+
+Many of perl's own test scripts exit 0 even if their TAP reports test
+failures, and some need particular setup (such as running from the right
+directory, or adding C<-T> to the command line). Hence if you want to bisect
+a test script, you can specify it with the I<--target> option, and it will
+be invoked using F<t/TEST> which performs all the setup, and exits non-zero
+if the TAP reports failures. This works for any file ending C<.t>, so you can
+use it with a file outside of the working checkout, for example to test a
+particular version of a test script, as a path inside the repository will
+(of course) be testing the version of the script checked out for the current
+revision, which may be too early to have the test you are interested in.
Because the test case is the complete argument to C<system>, it is easy to
run something other than the F<perl> built, if necessary. If you need to run
-the perl built, you'll probably need to invoke it as C<./perl -Ilib ...>
-
-You need a clean checkout to run a bisect, and you can't use the checkout
-which contains F<Porting/bisect.pl> (because C<git bisect>) will check out
-a revision before F<Porting/bisect-runner.pl> was added, which
-C<git bisect run> needs). If your working checkout is called F<perl>, the
-simplest solution is to make a local clone, and run from that. I<i.e.>:
+the perl built, you'll probably need to invoke it as C<./perl -Ilib ...>.
+As a special case, if the first argument of the test case is a readable file
+(whether executable or not), matching C<qr{\A#!./(?:mini)?perl\b}> then it
+will have C<./perl> <-Ilib> (or C<./miniperl>) prepended to it.
+
+You need a clean checkout to run a bisect. You can use the checkout
+containing F<Porting/bisect.pl> if you wish - in this case
+F<Porting/bisect.pl> will copy F<Porting/bisect-runner.pl> to a temporary
+file generated by C<File::Temp::tempfile()>. If doing this, beware that when
+the bisect ends (or you abort it) then your checkout is no longer at
+C<blead>, so you will need to C<git checkout blead> before restarting, to
+get the current version of F<Porting/bisect.pl> again. It's often easier
+either to copy F<Porting/bisect.pl> and F<Porting/bisect-runner.pl> to
+another directory (I<e.g.> F<~/bin>, if you have one), or to create a second
+git repository for running bisect. To create a second local repository, if
+your working checkout is called F<perl>, a simple solution is to make a
+local clone, and run from that. I<i.e.>:
cd ..
git clone perl perl2
Earliest revision to test, as a I<commit-ish> (a tag, commit or anything
else C<git> understands as a revision). If not specified, F<bisect.pl> will
-search stable perl releases until it finds one where the test case passes.
-The default is to search from 5.002 to 5.14.0. If F<bisect.pl> detects that
-the checkout is on a case insensitive file system, it will search from
-5.005 to 5.14.0
+search stable .0 perl releases until it finds one where the test case
+passes. The default is to search from 5.002 to the most recent tagged stable
+release (v5.18.0 at the time of writing). If F<bisect.pl> detects that the
+checkout is on a case insensitive file system, it will search from 5.005 to
+the most recent tagged stable release. Only .0 stable releases are used
+because these are the only stable releases that are parents of blead, and
+hence suitable for a bisect run.
=item *

+I<none>
+
+Don't build anything - just run the user test case against a clean checkout.
+Using this gives a couple of features that a plain C<git bisect run> can't
+offer - automatic start revision detection, and test case C<--timeout>.
+
+=item *
+
I<config.sh>
Just run F<./Configure>
run, as there is no target provided to just get things ready, and for 5.004
and earlier the tests run very quickly.

+
+A file ending C<.t>
+
+Build everything needed to run the tests, and then run this test script using
+F<t/TEST>. This is actually implemented internally by using the target
+I<test_prep>, and setting the test case to "sh", "-c", "cd t && ./TEST ..."

(Usually you'll use C<-e> instead of providing a test case in the

+non-option arguments to F<bisect.pl>. You can repeat C<-e> on the command
+line, just like you can with C<perl>)
C<-E> intentionally isn't supported, as it's an error in 5.8.0 and earlier,
which interferes with detecting errors in the example code itself.
=item *
+--crash
+
+Treat any non-crash as success, any crash as failure. (Crashing defined
+as exiting with a signal or a core dump.)
+
+=item *

=item *
+--valgrind
+
+Run the test program under C<valgrind>. If you need to test for memory
+errors when parsing invalid programs, the default parser fail exit code of
+255 will always override C<valgrind>, so try putting the test case invalid
+code inside a I<string> C<eval>, so that the perl interpreter will exit with 0.
+(Be sure to check the output of $@, to avoid missing mistakes such as
+unintended C<eval> failures due to incorrect C<@INC>)
+
+Specifically, this option prepends C<valgrind> C<--error-exitcode=124> to
+the command line that runs the testcase, to cause valgrind to exit non-zero
+if it detects errors, with the assumption that the test program itself
+always exits with zero. If you require more flexibility than this, either
+specify your C<valgrind> invocation explicitly as part of the test case, or
+use a wrapper script to control the command line or massage the exit codes.
+
+=item *
+
--test-build
Test that the build completes, without running any test case.
=item *
+--timeout I<seconds>
+
+Run the testcase with the given timeout. If this is exceeded, kill it (and
+by default all its children), and treat it as a failure.
+
+=item *
+
+--setpgrp
+
+Run the testcase in its own process group. Specifically, call C<setpgrp 0, 0>
+just before C<exec>-ing the user testcase. The default is not to set the
+process group, unless a timeout is used.
+
+=item *
+
+--all-fixups
+
+F<bisect-runner.pl> will minimally patch various files on a platform and
+version dependent basis to get the build to complete. Normally it defers
+doing this as long as possible - C<.SH> files aren't patched until after
+F<Configure> is run, and C<C> and C<XS> code isn't patched until after
+F<miniperl> is built. If C<--all-fixups> is specified, all the fixups are
+done before running C<Configure>. In rare cases adding this may cause a
+bisect to abort, because an inapplicable patch or other fixup is attempted
+for a revision which would usually have already I<skip>ped. If this happens,
+please report it as a bug, giving the OS and problem revision.
+
+=item *
+
+--early-fixup file
+
+=item *
+
+--late-fixup file
+
+Specify a file containing a patch or other fixup for the source code. The
+action to take depends on the first line of the fixup file
+
+=over 4
+
+=item *
+
+C<#!perl>
+
+If the first line starts C<#!perl> then the file is run using C<$^X>
+
+=item *
+
+C<#!/absolute/path>
+
+If a shebang line is present the file is executed using C<system>
+
+=item *
+
+C<I<filename> =~ /I<pattern>/>
+
+=item *
+
+C<I<filename> !~ /I<pattern>/>
+
+If I<filename> does not exist then the fixup file's contents are ignored.
+Otherwise, for C<=~>, if it contains a line matching I<pattern>, then the
+file is fed to C<patch -p1> on standard input. For C<=~>, the patch is
+applied if no lines match the pattern.
+
+As the empty pattern in Perl is a special case (it matches the most recent
+successful match) which is not useful here, the treatment of an empty pattern
+is special-cased. C<I<filename> =~ //> applies the patch if filename is
+present. C<I<filename> !~ //> applies the patch if filename missing. This
+makes it easy to unconditionally apply patches to files, and to use a patch
+as a way of creating a new file.
+
+=item *
+
+Otherwise, the file is assumed to be a patch, and always applied.
+
+=back
+
+I<early-fixup>s are applied before F<./Configure> is run. I<late-fixup>s are
+applied just after F<./Configure> is run.
+
+These options can be specified more than once. I<file> is actually expanded
+as a glob pattern. Globs that do not match are errors, as are missing files.
+
+=item *

--no-clean
Tell F<bisect-runner.pl> not to clean up after the build. This allows one

-Test that all stable revisions can be built. By default, attempts to build
-I<blead>, I<v5.14.0> .. I<perl-5.002> (or I<perl5.005> on a case insensitive
-file system). Stops at the first failure, without
-cleaning the checkout. Use I<--start> to specify the earliest revision to
-test, I<--end> to specify the most recent. Useful for validating a new

+Test that all stable (.0) revisions can be built. By default, attempts to

Validate that the test case isn't an executable file with a

+F<perl>, not the F<perl> built by the bisect runner. Likely this is not what
+you wanted. If your test case is actually a wrapper script to run other
commands, you should run it with an explicit interpreter, to be clear. For
example, instead of C<../perl/Porting/bisect.pl ~/test/testcase.pl> you'd
run C<../perl/Porting/bisect.pl /usr/bin/perl ~/test/testcase.pl>
